Hi @gluparel, @apalasciano and @singhra1994 !

In this PR, the most important changes are:

MC Gen Data Model Extensions:

  • Introduced new tables: DstarHadronMcGenPair for D*-hadron MC Gen pairs and DstarHadronGenInfo for associated MC Gen information.

MC Gen Pair Building Logic:

  • Implemented processSeMcGen and processMcGenME functions in correlatorDstarHadrons.cxx to build D*-hadron pairs at MC Gen same-event and mixed-event levels, respectively.
  • Registered new output tables for MC Gen pairs in the correlator.

MC Gen Histogramming in Analysis Task:

  • Added new THnSparse for MC Gen correlations (inclusive, prompt, non-prompt) in the analysis task.

Work is in progress and let me know if any suggestion or changes are required. Thanks
